As Jasmine Koo headed home from last year’s Toyota Junior Golf World Cup supported by Japan Airlines, she voiced a desire to come back and “conquer” Chukyo Golf Club in the way Japan’s titleholders had.

Consider it mission accomplished.

Even with a couple of slips down Friday’s stretch, Koo not only repeatedly put her stamp on the record book in capturing the girls’ individual title but was the catalyst that emphatically ended the United States’ title drought with a stunning 11-shot romp.

“This is probably the biggest junior event there is,” said Koo, whose closing 2-under-par 70 also gave her the event’s 54-hole scoring record. “To come back and win it — this is so special because golf (can be) such an individual sport.

“I think the individual title is great,” she added, “but the happiness comes from our team winning. Our entire team can share in it.”

The U.S. boys very nearly made it a double triumph, actually tying Korea at the top of the team leaderboard but falling short in a tiebreaker. With two of three scores counting each day toward the team total, the first tiebreaker was Friday’s third score — where Korea’s Jaehyun Park bested Jackson Byrd by two.
